FIDUCCIA SNOW AND ICE MELTING MACHINE 2 SHEETS'SHEET 2Filed Nov. 29, 1949 INVENTOR ANTHONY FIDUCCIA W l/ls ATTORNEY PatentedNov. 27, 1951 UNITED STATES PATENT OFFICE 6 Claims.

This invention relates to snow and ice melting machines in general suchas disclosed in the United States Patent No. 2,471,733, issued May 31,1949, to this applicant.

Among the objects of the present invention it is aimed to provide animproved snow and ice melting machine having a main snow and icereceiving container to receive the water from the melted snow in thebottom thereof, a second con tainer in said main container above thelevel of the water having foraminous converging side walls with adeflector in the middle thereof to intercept the opposing flames anddeflect the same into the snow and ice supply as it is introduced, inthe interest of a maximum efficiency, that is, to obtain a maximum useof the heat generated by the burners.

It is still another object of the present invention to provide animproved snow and ice melting machine such as disclosed in the UnitedStates Patent No. 2,471,733 of this applicant in which the water fromthe melted snow received in the bottom; of the main container is pumpedup through a heater to a supply conduit having a plurality of dischargeopenings at the upper edge of the container whereby advantage is takenof the heat generated in the conduit and in the heated water dischargingtherefrom to melt the snow and ice as quickly as it is received andprevent it from accumuTating along the upper edges of the container.

These and other features, capabilities and advantages of the inventionwill appear from the subjoined detailed description of one specificembodiment thereof illustrated in the accompanying drawings, in whichFig. 1 is a plan view with parts broken away of the improved snow andice melting machine.

Fig. 2 is a transverse section of the same Fig. 3 is a section on theline 3-3 of Fig. 2.

In the embodiment shown, there is provided a trough l, arcuate intransverse cross section as shown in Fig. 2, with flanges 2 at the upperfree ends thereof extending outwardly to rest on the angle iron frame 3,in turn supported on the rectangular frame 4 mounted on the upper web ofthe channel iron frame 5 constituting part of the chassis of a truck,trailer or the like.

Supported on the upper web of the rear transverse cross piece of theframe 5 and extending upwardly therefrom, there are provided two angleiron uprights B which are secured to the ends of the heat insulated sidewall members 1. The front ends of the wall members i in turn are securedto the angle iron uprights 8 extending CJI upwardly from and supportedon the upper faces of the upper webs of the frame 5. The upper free endsof the uprights 6 and 8 in turn may be connected by a rectangular angleiron frame 3 on which rest the outwardly extending flanges ll] of theimpervious metal apron H having short inwardly and downwardly flaringextensions l2 at their sides and rear, and a comparatively long inwardlyand downwardly flaring extension is at its front end. The extension l2in turn terminate in vertical extensions I4 having inwardly extendingflanges H5 in line with the inwardly extending flange l6 of theextension l3 to form a support for the outwardly extending web of theangle iron frame H at the upper edge of the foraminous extension l8having inwardly and downwardly flaring side wall members I9 andvertically extending impervious end wall members 29. The side wallmembers l9 at their lower ends are spaced from one another and havesupported on the inner edges thereof the lower diverging ends of thetapering impervious deflector sections 21. The sections 2| as shown areprovided with two impervious wall members 22 converging into engagementwith one another at their upper'ends.

Extending downwardly and outwardly from the insulated walls'l, there areprovided the two outwardly and downwardly flaring supporting frames 23having an opening below the edge 24, which opening, however, may becovered, as shown at the left side of Fig. 2, by the cover 25 hingedlyconnected at 26 to the frames 23 at the edges 24 thereof. These covers25 may be maintained in raised or open position by any suitable means,such as the chain 21, connecting the lower edge of the cover 25 with theangle iron frame 9.

Extending inwardly from the walls I there are provided the brackets 28.From the lower ends of the brackets 28 to the supporting frames 23, inthe present instance, there are provided a plurality of rails 29 to forma support for suspendingly securing the burners 30 and 3|, the burners30 being disposed as shown in Fig. 1 to direct flames at the foraminousextensions l9, and the burners 3| to direct flames at the two sets ofheating coils 32 and 33. The heating coils 32 and 33 are connected attheir lower ends to the inner conduit 34 having a drain connection 35which may be shut off by the valve 36 and also having a connection 31 tothe water pump 38 which is connected by the conduit 39 with the inletcylinder 40 disposed in the trough I below the normal level of the watertherein as shown. The shaft of the pump 38 is provided with a Forinsuring that the level of the water in the,

trough I does not exceed a predetermined height, that shown in Figs. 2and 3 as anifistsnce, adisfcharge inlet 48 is located at a predeterminedaltitude above the level of the inlt'cylinder 40" in the trough Iconnected to. the inner discharge.

conduit 49 which extends out of the. trough I into connection with theconduit 50 which is con-' nected to the. water pump having the dischargeconduit 52 connected to-the conduit 53 extending rearwardly andterminating at 54 for connection to a hose or the like to facilitatedirecting the waterdischalfged to asewer or the like; The shaft of thepump 5| is provided with the sheave 55 drivingly connected by the belt56 to the driven shaft 43. Consequently when the clutch 45 is actuatedtoconnect the driven shaft 43 with the motor 44, not only the pump 38 butalso the pump 5| will be actuated.

The fuel to the burners-3H and 3| in turn is ll plied under pressure andis fed to theburners 3ll'a'nd 3| by thepump 51, the shaft of which isprovided with the sheave 58 which is 'drivingly connected by the belt 59with the sheave 60 of the motor 44. The pump 5'! in turn is connected tothe fuel supply line 6| and with the connection 62' for sup-plying thefuel to the fuel conduits 33 and-64 which preferably are supported onthe angle iron rails 65 secured to the chan nel iron frame 5. Theconduits 63 and B4 in turn are connected by the flexible extensions 66to the burners 30 and 3|.

As-sh'own, whenthe burners 30 and 3| are not in use, they may be movedup into the position shown at the left hand side of Fig. 2, and thecover 25 lowered-into'the position shown. In turn, when the-burners 3Uand-3I are to be used theyare slidably moved to the position desired,secured inplace, and the cover 25anchored in the raised position shownat the right hand side Fig.2. r

-'The deflector- 2| serves to deflect the flames from the burner 30upwardly intothe mass of snow and ice being received, and to. protectthe opposing walls of theflforaminous extension l3. from overheating.

Preferably the trough l as shown is also provided with a drain 6'!controlled by the valve. 68. Similarl the rearwallof the trough l isprovided with a sludge cleanoutdoor 69 as shown inv Fig. 2. V

It. is obvious that various changes and modifications may be made to thedetails of construction withoutdep rtin f m e e er l S r of theinvention as set forth in theappended claims.
